CAUTION
A signal name with a rule above it indicates an “L” active signal.
Bidirectional communications cannot take place, unless all signal names for both sides
correspond to each other.
Connect all signal lines using a twisted-pair cable. Connect the return side to the signal ground
level.
Make sure the signals satisfy electrical characteristics.
Set the leading edge and trailing edge times to 0.5ms or less.
Do not ignore Ack
or BUSY signals during a data transfer. Ignoring such signals may result in
data corruption.
Make the interface cables as short as possible.
Transmission standard ISO14443 A
Frequency 13.56 MHz
Resonance frequency 14.30 Hz±0.55 MHz
Memory 144 byte
Transmission distance Approximately 10 mm from the NFC installation location.
When UB-R04 is installed, you cannot use the printer's built-in NFC. Install the NFC tag for the UB-R04
at a location that is remote from the printer's built-in NFC.
The transmission distance is an estimate that depends on our experiment conditions and is not a
guaranteed value.
It varies based on the installation environment and target device.
